[BC] recommended fluxes for silver soldering ground system/radials?

[Neal Newman]

 I  Just wire brush the copper to clean it. and use a Plumbers Actlyene B-tank with a Turbo Torch Tip. with Silver solder Rods...  I Never use Flux when Brazing #10 wire radials  to strap. I have found in some locations the B-Tank alone wont get hot enough.. Then I add the Oxy tank... works every time.
